Project Abstract 

The HYDRORIFT experiment is part of the French project GEOFLUX that aims at understanding the behaviour of fluids in the deep upper crust using a range of different methods (e.g. in situ geophysical data, 3A-press rock mechanics experiments, physical, numerical and analogical modelling) The GEORG project (Geothermal research group) and HS ORKA support the project. The HYDRORIFT experiment involves both ISOR (Iceland GeoSurvey) and a group of French GEOFLUX scientists in a geophysical experiment on the Reykjanes Peninsula in Iceland including both high-resolution TEM/MT studies and seismic tomography. This study follows a previous successful five-month seismic experiment in the same area (Geoffroy and Dorbath, 2008). The objective is to better stress the significance of the velocities anomalies discovered in the area following the 2005 experiment (notably beneath Kleifarvatn Lake) and to reach a more accurate physical knowledge of the geometry and timeevolution of the different fluid reservoirs within the active rift zone in Iceland. An array of 30 seismic stations, including three broadbands, was deployed in May 2009 for a six-month period. We present the details of the new seismic experiment as well as our first results mixed with those of the 2005 experiment.

Project finished in 2013
